Conjoint Associations of Adherence to Physical Activity and Dietary Guidelines With Cardiometabolic Health: The Framingham Heart Study.

Background The conjoint associations of adherence to the recent physical activity and dietary guidelines with the metabolic syndrome (MetS) are incompletely understood. Methods and Results We evaluated 2379 FHS (Framingham Heart Study) Third Generation participants (mean age, 47 years; 54.4% women) attending examination cycle 2. We examined the cross-sectional relations of adherence to the 2018 Physical Activity Guidelines for Americans (binary; moderate-to-vigorous physical activity ≥150 versus <150 min/wk) and 2015 Dietary Guidelines for Americans (binary; 2015 Dietary Guidelines for Americans Adherence Index ≥median versus

Exercise Reduces Medication for Metabolic Syndrome Management: A 5-Year Follow-up Study.

PURPOSE: This study aimed to determine the effects of a 5-yr exercise intervention on metabolic syndrome (MetS) and health-related variables and medication use for MetS management. METHODS: Participants were randomly assigned to an exercise intervention (n = 25, 54 ± 2 yr, 20% women) or control group (n = 26, 54 ± 2 yr, 38% women). The intervention lasted 4 months per year and consisted of high-intensity interval training on a cycloergometer thrice a week. Outcomes were MetS z-score and medication use score, MetS-related variables (including blood pressure, blood glucose homeostasis, and lipid profile), and cardiorespiratory fitness (CRF, as determined by maximal oxygen uptake). RESULTS: MetS z-score was similarly reduced over time in both groups (P = 0.244 for group-time interaction). A quasi-significant and significant group-time interaction was found for MetS number of factors (P = 0.004) and CRF (P < 0.001), respectively. Thus, MetS factors tended to decrease over time only in the exercise group with no change in the control group, whereas CRF increased from baseline to 5-yr assessment in the exercise group (by 1.1 MET, P < 0.001) but decreased in the control group (-0.5 MET, P = 0.025). Medicine use score increased twofold from baseline to 5-yr follow-up in the control group (P < 0.001) but did not significantly change (10%, P = 0.52) in the exercise group (P < 0.001 for group-time interaction). The proportion of medicated patients who had to increase antihypertensive (P < 0.001), glucose-lowering (P = 0.036), or total medication (P < 0.0001) over the 5-yr period was lower in the exercise than that in the control group. CONCLUSIONS: Exercise training can attenuate the increase in medication that would be otherwise required to manage MetS over a 5-yr period.

Effects of peripheral and different inspiratory muscle training methods in coronary artery disease patients with metabolic syndrome: A randomized-controlled trial.

Background OBJECTIVE: To investigate the effects of peripheral muscle training (PMT) and different inspiratory muscle training (IMT) methods on respiratory functions, exercise capacity, and biochemistry parameters in coronary artery disease patients with metabolic syndrome. METHODS: This prospective, single-blind, randomized-controlled study included 60 patients of stable coronary artery disease with metabolic syndrome (New York Heart Association [NYHA] Class I-II, left ventricular ejection fraction >40%). Patients were randomly divided into three groups: neuromuscular electrical stimulation (NMES) plus PMT group (NMES + PMT group, n = 20), IMT plus PMT group (IMT + PMT group, n = 20) and PMT group (PMT group, n = 20). Treatment continued for six weeks for all groups. The NMES was applied to rectus abdominis, IMT was applied with 30% of maximal inspiratory pressures, and PMT was applied at home. Spirometry, maximal inspiratory and expiratory pressure, dyspnea scores, exercise stress test, and biochemistry parameters were measured before and after training. RESULTS: There were significant improvements in spirometric tests, respiratory muscle strength, dyspnea scores, exercise capacity, fasting blood glucose, and antistreptolysin O after treatment in all groups (p < 0.05). Significant improvements in C-reactive protein and erythrocyte sedimentation rate were observed in NMES + PMT and IMT + PMT groups (p < 0.05). Among the groups, there was a significant difference in maximal inspiratory pressure (p = 0.02) and erythrocyte sedimentation rate (p = 0.037) in favor of NMES + PMT group (p < 0.05). CONCLUSION: Our study results showed significant improvements in respiratory functions, exercise capacity, and biochemistry markers in all groups. Different IMT methods can be used in cardiopulmonary rehabilitation to improve exercise intolerance in coronary artery disease patients with metabolic syndrome. CLINICAL TRIAL REGISTRATION NUMBER: NCT03523026.

Metabolic Syndrome in Children and Adolescents: Diagnostic Criteria, Therapeutic Options and Perspectives.

PURPOSE OF REVIEW: This review summarizes our current understanding of the metabolic syndrome (MetS) in children and adolescents. Special emphasis is given towards diagnostic criteria and therapeutic options. RECENT FINDINGS: Consistent diagnostic criteria to define MetS in childhood and adolescence are not available to date. There is common agreement that the main features defining MetS include (1) disturbed glucose metabolism, (2) arterial hypertension, (3) dyslipidemia, and (4) abdominal obesity. However, settings of cut-off values are still heterogeneous in the pediatric population. Additional features that may define cardiometabolic risk, such as non-alcoholic fatty liver disease (NAFDL) or hyperuricemia, are not considered to date. Prevalence of childhood obesity has more than doubled since 1980, and 6-39% of obese children and adolescents already present with MetS, depending on the definition applied. There is common agreement that a consistent definition of MetS is urgently needed for children to identify those at risk as early as possible. Such definition criteria should consider age, gender, pubertal stage, or ethnicity. Additional features such as NAFDL or hyperuricemia should also be included in MetS criteria. Lifestyle modification is still the main basis to prevent or treat childhood obesity and MetS, as other therapeutic options (pharmacotherapy, bariatric surgery) are not available or not recommended for the majority of affected youngster.

High-intensity interval training improves metabolic syndrome and body composition in outpatient cardiac rehabilitation patients with myocardial infarction.

BACKGROUND: To examine the effect of high-intensity interval training (HIIT) on metabolic syndrome (MetS) and body composition in cardiac rehabilitation (CR) patients with myocardial infarction (MI). METHODS: We retrospectively screened 174 consecutive patients with MetS enrolled in CR following MI between 2015 and 2018. We included 56 patients who completed 36 CR sessions and pre-post dual-energy X-ray absorptiometry. Of these patients, 42 engaged in HIIT and 14 in moderate-intensity continuous training (MICT). HIIT included 4-8 intervals of high-intensity (30-60 s at RPE 15-17 [Borg 6-20]) and low-intensity (1-5 min at RPE < 14), and MICT included 20-45 min of exercise at RPE 12-14. MetS and body composition variables were compared between MICT and HIIT groups. RESULTS: Compared to MICT, HIIT demonstrated greater reductions in MetS (relative risk = 0.5, 95% CI 0.33-0.75, P < .001), MetS z-score (- 3.6 ± 2.9 vs. - 0.8 ± 3.8, P < .001) and improved MetS components: waist circumference (- 3 ± 5 vs. 1 ± 5 cm, P = .01), fasting blood glucose (- 25.8 ± 34.8 vs. - 3.9 ± 25.8 mg/dl, P < .001), triglycerides (- 67.8 ± 86.7 vs. - 10.4 ± 105.3 mg/dl, P < .001), and diastolic blood pressure (- 7 ± 11 vs. 0 ± 13 mmHg, P = .001). HIIT group demonstrated greater reductions in body fat mass (- 2.1 ± 2.1 vs. 0 ± 2.2 kg, P = .002), with increased body lean mass (0.9 ± 1.9 vs. - 0.9 ± 3.2 kg, P = .01) than the MICT. After matching for exercise energy expenditure, HIIT-induced improvements persisted for MetS z-score (P < .001), MetS components (P < .05), body fat mass (P = .002), body fat (P = .01), and lean mass (P = .03). CONCLUSIONS: Our data suggest that, compared to MICT, supervised HIIT results in greater improvements in MetS and body composition in MI patients with MetS undergoing CR.

Impact of lifestyle modification on some components of metabolic syndrome in persons with severe mental disorders: A meta-analysis.

BACKGROUND: Metabolic syndrome (MS) is reportedly associated with high mortality from mostly cardiovascular causes in patients with severe mental disorders (SMD). Lifestyle interventions augment effective management of MS in patients with SMD. The present meta-analysis aims at updating the recent evidence on the effectiveness of lifestyle intervention for MS in patients with SMD. METHOD: A literature search for English Language publications of randomized controlled trials (RCTs) from 2001 to 2016 comparing lifestyle modification (LM) with treatment as usual (TAU) in the management of MS were identified. Using PRISMA guidelines, 19 RCTs reporting data on 1688 SMD and MS patients and providing data on change in Body Weight, Body Mass Index (BMI) and waist circumference (WC) were included. Using random effects model, standardized mean difference between LM and TAU for the mean baseline-to-endpoint change in body weight, BMI and WC was calculated with a 95% confidence limit, on RevMan 5.3. The study was registered with PROSPERO (CRD42016046847). RESULTS: LM had significantly superior efficacy in the reducing weight (-0.64, 95% CI -0.89, -0.39, Z = 5.03, overall effect p < 0.00001), BMI (-0.68, 95% CI -1.01, -0.35, Z = 4.05, overall effect p < 0.0001), and WC (-0.60, 95% CI -1.17, -0.03, Z = 2.06; overall effect p = 0.04), compared to TAU. LM was significantly more effective than TAU even in short duration (p = 0.0001) and irrespective of the treatment setting. CONCLUSION: Interventions targeting LM in persons with SMD and MS are effective in reducing body weight, BMI and WC. It must be routinely recommended to all patients with SMD, ideally during commencement stage of second generation antipsychotic treatment.

Evaluation of the Role of Balneotherapy in Rehabilitation Medicine.

Balneotherapy is a treatment with healing waters, which includes bathing and physiotherapy in thermal water, therapeutic drinks, medical massage, and water jet massage. It is based on the buoyancy, physical properties, temperature, and chemical effects of mineral water. Throughout European and Japanese medical institutions, balneology and hot spring therapy is very much a part of routine medical treatment. The mechanism of balneotherapy is not yet completely understood. Balneotherapeutic procedures are mainly performed for the prevention, treatment, and rehabilitation of musculoskeletal diseases, but they have also proven useful for various other indications such as for the treatment or rehabilitation of dermatological diseases, immuno-inflammatory diseases, chronic pain syndromes, chronic cardiac diseases, and metabolic syndromes or neurological diseases as well as in the rehabilitation of patients with psychiatric conditions. Balneotherapy works well in the case of muscle tension, as it is relieving and relaxing, and it may be associated with improvement of various diseases. However, further investigations are necessary to determine the effectiveness, safety, standard procedures, and potential side effects of balneotherapy.

Self-management education for rehabilitation inpatients: A cluster-randomized controlled trial.

OBJECTIVE: To evaluate generic self-management modules (SelMa) as an adjunct to disease-specific educational programs during inpatient medical rehabilitation. METHODS: A bi-center cluster-randomized controlled trial with 698 patients with coronary artery disease, metabolic syndrome, or inflammatory bowel disease was conducted. We compared two versions of SelMa, a group with 3 h or a lecture with 1 h, respectively, in addition to disease-related patient education, to usual care (only disease-related education). SelMa aims at providing skills that may help implementing health behavior. The primary outcomes were goal setting and behavior planning at discharge and goal attainment and health behavior at 6- and 12-months follow-up. Secondary outcomes included motivation, knowledge and self-management competences. RESULTS: At discharge, SelMa group, but not SelMa lecture, proved superior to usual care regarding goal setting (p = 0.007, d = 0.26), but not behavior planning (p = 0.37, d = 0.09). Significant effects were also observed on several secondary outcomes. At later follow-up, however, no effects on primary outcomes emerged. Participants' satisfaction was higher in the group than the lecture format. CONCLUSIONS: These short modules did not succeed in improving self-management skills in the long-term. PRACTICE IMPLICATIONS: A self-management group may foster self-management skills in short term. Interventions should be developed to increase sustainability of effects.

Physical activity mitigates adverse effect of metabolic syndrome on vessels and brain.

Metabolic syndrome (MetS) adversely affects the vasculature and cerebral white matter (CWM) integrity. Arterial stiffening has been associated with diminished CWM integrity. Physical activity (PA) can ameliorate components of MetS and subsequently affect arterial stiffening and CWM integrity. Our aim was to determine the role of PA on mitigating the adverse influence of MetS on arterial stiffness and CWM integrity. In a cross-sectional study design, sixty-six middle-aged adults (40-62 years) composed of 18 sedentary MetS (Sed MetS), 21 physically active MetS (Active MetS), and 27 healthy individuals absent of MetS risk factors were studied. Carotid artery stiffness was assessed via simultaneous ultrasound and tonometry. CWM integrity was measured using diffusion tensor imaging (DTI) through metrics of fractional anisotropy (FA) and mean diffusivity (MD). Carotid ß-stiffness index in Active MetS was lower than Sed MetS but was not different from Healthy controls (6.6 ± 1.5, 7.7 ± 2.1, and 5.6 ± 1.6 au, p = 0.001). CWM integrity was significantly greater in Active MetS subjects compared to Sed MetS subjects but statistically equal to Healthy controls in the anterior limb of the internal capsule, and splenium of the corpus callosum, uncinate fasciculus, and superior corona radiata (all p < 0.05). Middle-aged individuals with MetS who habitually perform PA demonstrated lower arterial stiffness and more favorable CWM integrity than their sedentary peers, indicating that PA may be effective in mitigating the adverse effects of MetS on the vasculature and brain at midlife.

[Evaluation of the effectiveness of rehabilitation of elderly patients with metabolic syndrome, taking into account the provisions of International classification of functioning, disability and health.]

The article contains data on rehabilitation measures in elderly patients with metabolic syndrome. Individual-oriented treatment and rehabilitation programs implemented in primary health care allow to reliably reduce the severity and risk of progression of restrictions of life, increase the independence of patients The elderly, having metabolic syndrome, complicated the development of type 2 diabetes mellitus. It is proposed to assess the effectiveness of rehabilitation, taking into account the provisions of the International Classification of functioning, restrictions on life and health and by drawing up an individual geriatric profile.

Obesity and metabolic syndrome in COPD: Is exercise the answer?

Approximately half of all patients with chronic obstructive pulmonary disease (COPD) attending pulmonary rehabilitation (PR) programmes are overweight or obese which negatively impacts upon dyspnoea and exercise tolerance particularly when walking. Within the obese population (without COPD), the observed heterogeneity in prognosis is in part explained by the variability in the risk of developing cardiovascular disease or diabetes (cardiometabolic risk) leading to the description of metabolic syndrome. In obesity alone, high-intensity aerobic training can support healthy weight loss and improve the constituent components of metabolic syndrome. Those with COPD, obesity and/or metabolic syndrome undergoing PR appear to do as well in traditional outcomes as their normal-weight metabolically healthy peers in terms of improvement of symptoms, health-related quality of life and exercise performance, and should therefore not be excluded. To broaden the benefit of PR, for this complex population, we should learn from the extensive literature examining the effects of exercise in obesity and metabolic syndrome discussed in this review and optimize the exercise strategy to improve these co-morbid conditions. Standard PR outcomes could be expanded to include cardiometabolic risk reduction to lower future morbidity and mortality; to this end exercise may well be the answer.

Low Normalized Grip Strength is a Biomarker for Cardiometabolic Disease and Physical Disabilities Among U.S. and Chinese Adults.

BACKGROUND: Evidence highlights the importance of muscular strength as a protective factor for health and function across aging populations. The purpose of this study was to examine the extent to which low normalized grip strength (NGS) serves as a biomarker for both cardiometabolic disease and physical disability in U.S. and Chinese adults. METHODS: Middle aged and older adults from the U.S. National Health and Nutrition Examination Survey 2011-2012 and 2013-2014 combined surveys (n = 4,544), and the 2011 wave of the China Health and Retirement Longitudinal Study (n = 6,030) were included. Strength was assessed using a handgrip dynamometer, and was normalized to body mass. Weighted logistic regression models were used to assess the association between NGS and diabetes, hyperglycemia, hypertriglyceridemia, low HDL-cholesterol, hypertension, and physical disability status, while controlling for age, sex, and sociodemographic characteristics. RESULTS: Every 0.05 lower NGS was independently associated with a 1.49 (95% confidence interval [CI]: 1.42-1.56) and 1.17 (95% CI: 1.11-1.23) odds for diabetes; a 1.46 (95% CI: 1.39-1.53) and 1.11 (95% CI: 1.07-1.15) odds of hyperglycemia; a 1.15 (95% CI: 1.07-1.25) and 1.11 (95% CI: 1.08-1.14) odds of hypertriglyceridemia; a 1.22 (95% CI: 1.17-1.27) and 1.15 (95% CI: 1.12-1.18) odds of low HDL-cholesterol; a 1.19 (95% CI: 1.14-1.24) and 1.10 (95% CI: 1.07-1.14) odds of hypertension; and a 1.36 (95% CI: 1.29-1.42) and 1.10 (95% CI: 1.05-1.15) odds for physical disability status in U.S. and Chinese adults, respectively. CONCLUSIONS: NGS was robustly associated with both cardiometabolic disease risk and physical disabilities in U.S. and Chinese aging adults.

The effects of a lifestyle intervention program on physical outcomes, depression, and quality of life in adults with metabolic syndrome: A randomized clinical trial.

BACKGROUND/OBJECTIVES: Lifestyle modification is recommended as the primary intervention for metabolic syndrome (MetS). The study was to examine the effects of a lifestyle intervention program (LIP) on physical outcomes, depression, and quality of life (QoL) in Chinese adults with MetS. METHODS: A randomized control trial design was used. A three-month LIP guided by the Health Promotion Model was developed, including a lifestyle modification booklet, one session of discharge education, and six telephone follow-ups. Patients with MetS were recruited from the inpatient departments of a hospital and were randomized to receive either the LIP or usual care. The physical outcomes, depression (Depression subscale of Hospital Anxiety and Depression Scale), and QoL (Medical Outcome Study Short Form-12, SF-12) were measured at baseline, one-month (T1) and three-month (T2). The effects of the LIP were examined by the generalized estimating equation (GEE) model. RESULTS: The study recruited 173 participants, with 86 in the intervention group and 87 in the control. Continuous improvements were observed in all the study outcomes in the intervention group. The GEE model revealed significant improvements in body weight (T1: p=0.017, T2: p=0.007), body mass index (T1: p=0.015, T2: p=0.009), depression (T1: p=0.027, T2: p<0.001), and physical aspects of QoL at T2 (p=0.02). CONCLUSIONS: The current LIP was effective in losing body weight, improving depression and QoL of MetS populations in three-month observation. Considering its low-cost and convenience, the LIP could be applied in clinical practice to improve patient outcomes.

Yoga for metabolic syndrome: A systematic review and meta-analysis.

Background Metabolic syndrome is the most important risk factor for developing cardiovascular disease and type 2 diabetes. The aim of this review was to systematically assess and perform a meta-analysis of the effects of yoga on the parameters of metabolic syndrome. Methods MEDLINE/PubMed, Scopus, the Cochrane Central Register of Controlled Trials and IndMED were searched and screened from their inception through to 8 March 2016 for randomised controlled trials on yoga for patients with metabolic syndrome. Risk of bias was assessed using the Cochrane risk of bias tool. Results Seven trials with a total of 794 participants were included. No effects of yoga on resolution of metabolic syndrome, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol and fasting plasma glucose were found, but yoga was superior to usual care for waist circumference (standardised mean difference (SMD) = -0.35; 95% confidence interval (CI) = -0.57 to -0.13; p < 0.01) and systolic blood pressure (SMD = -0.29; 95% CI = -0.51 to -0.07; p = 0.01). However, these effects were not robust against selection bias. No intervention-related adverse events were reported. Conclusion Based on the results of this meta-analysis, no recommendation can be made for or against yoga in order to influence the parameters of metabolic syndrome. Despite methodological drawbacks, and until further research is undertaken, yoga can be preliminarily considered as a safe and effective intervention for reducing waist circumference and systolic blood pressure in individuals with metabolic syndrome who are not adhering to conventional forms of exercise.

Effectiveness of community-based exercise intervention programme in obese adults with metabolic syndrome.

AIMS AND OBJECTIVES: The objective of this study was to change the anthropometric, clinical, biochemical indicators and the rate of metabolic syndrome among obese adults in community. BACKGROUND: Obesity is an indicator of metabolic syndrome and cardiometabolic diseases. Obesity increases national health care expenditure in Taiwan. The high prevalence of obesity is not only a public health issue but also an economic problem. Changes in lifestyle can help to prevent metabolic syndrome for individuals with obesity. DESIGN: A randomised controlled trial was applied. METHODS: In this randomised controlled trial by location, 136 metabolically abnormal obese individuals were included. The related indicators with metabolic syndrome were measured at baseline and after six months. The experimental group participated in a six-month community-based programme including provided exercise environments, exercise skills and volunteers' reminding. The control group was only provided environment and skills. RESULTS: One hundred and thirty-one participants completed this trail. In comparison with the baseline, the intervention group showed a significant increase in high-density lipoprotein cholesterol (2·34 mg/dl), and decrease in body weight (1·09 kg), waist circumference (3·63 cm), systolic blood pressure (10·52 mmHg), diastolic blood pressure (5·21 mmHg), fasting blood glucose (5·84 mg/dl) and body mass index (0·74 kg/m(2) ). In the control group, significant decrease in body mass index and waist circumference were discovered. Compared to the changes between the two groups, the results showed there were significant differences in waist circumference, systolic blood pressure, diastolic blood pressure and high-density lipoprotein cholesterol. CONCLUSIONS: The community-based intervention could help to improve high-density lipoprotein cholesterol, reduce body weight, body mass index, waist circumference, blood pressure and fasting blood glucose in metabolically abnormal obese. RELEVANCE TO CLINICAL PRACTICE: This community-based programme helped metabolically abnormal obese individuals become metabolically healthy. In the future, community nurses will work with village heads and volunteers. They can encourage residents in the communities to have healthy lifestyle. As a result, the goal of this programme will be successfully achieved with less time and effort.

Nordic walking in the second half of life.

OBJECTIVES: The objective of this article is to review the literature regarding the effectiveness and safety of Nordic walking (NW) in therapeutic rehabilitation in patients of an advanced age. METHODS: Randomized studies comparing NW with different patterns of long-lasting physical rehabilitation in older adults (average age 65 years) were selected for the review. Studies were identified through a Medline database search covering the last 21 years. RESULTS: Seventy-four studies on this subject were identified, 37 of them fulfilled the required criteria and 27 of these were analyzed in this review. DISCUSSION: Nordic walking provides a safe and effective way to enhance physical activity in the elderly. It could also serve as a method of rehabilitation that improves fitness, the performance and the exercise capacity of aged persons with diseases associated with an advanced age: cardiovascular diseases due to atherosclerosis; metabolic syndrome without diabetes; early stage Parkinson's disease; chronic obstructive pulmonary disease and lowering depression in women with Sjögren's Syndrome.

Impact of lifestyle modification on left ventricular function and cardiopulmonary exercise capacity in patients with heart failure with normal ejection fraction and cardiometabolic syndrome: a prospective interventional study.

BACKGROUND: Heart failure with normal left ventricular ejection fraction (HFNEF) accounts for about one third of all heart failure patients with considerable mortality. The metabolic syndrome (MS) is a risk factor for diastolic dysfunction and HFNEF. We hypothesized that modifying metabolic burden by exercise training and weight loss might improve left ventricular diastolic function, heart failure symptoms and rehospitalization rate. METHODS AND RESULTS: Forty patients with HFNEF, MS and prediabetes were enrolled in this prospective study. Echocardiography and cardiopulmonary exercise testing (CPET) were done at baseline and after 3 months lifestyle modification (LSM). NT-pro BNP and adiponectin were determined at baseline as both peptidehormones play a crucial role in MS and heart failure. After discharge a 3-month LSM program with the aim of weight reduction by diet and exercise was started. After the intervention period a weight reduction of ≥ 2% was defined as successful LSM (group A = 23 patients), while a weight reduction < 2% was classified as unsuccessful LSM (group B = 17 patients). At baseline NT-pro BNP (424 ± 381 versus 121 ± 99 pg/ml, P < 0.01) and adiponectin (10.1 ± 6.2 versus 4.6-2.0 µg/ml, P < 0.01) were higher in group A than in group B. After 3 months of LSM, CPET showed a significant improve- ment of VO2 peak (P < 0.01), EqCO2 (P < 0.001), O2-pulse (P = 0.02) and VE / VCO2 slope (P = 0.01) in group A. After one year of follow-up a modest but significant reduction of left atrial size and mitral flow to mitral annulus velocity ratio E/E' was seen in group A. LSM resulted in significant improvement of NYHA status (P = 0.03) and higher freedom of rehospitalization (P = 0.04) in group A. CONCLUSION: Successful lifestyle modification in obese, prediabetic patients with HFNEF improves diastolic left ventricular function and cardiopulmonary exercise capacity. As these measures result in improved NYHA status and less hospitalization, LSM might be a promising approach to prevent chronic diastolic heart failure.

Factores predictores de resolución de la resistencia a la insulina con la cirugía de banda gástrica ajustable / Predictive factors of insulin resistance resolution with adjustable gastric band surgery

INTRODUCCIÓN: El objetivo del estudio ha sido evaluar factores preoperatorios relacionados con remisión de la diabetes y pérdida de peso tras cirugía de banda gástrica ajustable por vía laparoscópica. MATERIAL Y MÉTODOS: Se incluye una cohorte retrospectiva de 95 pacientes a los que se colocó banda gástrica ajustable. Se realizó un estudio preliminar descriptivo de factores pronósticos mediante el modelo de regresión logística con SPSS 17.0. Las variables independientes fueron edad, sexo, índice de masa corporal (IMC), estado de diabetes y grado de obesidad; las variables dependientes fueron proporción de peso perdido, variación del diabetes status score y porcentajes de variación en la glucemia basal y en la hemoglobina glucosilada. RESULTADOS: Las variables que presentaron relación estadísticamente significativa con los porcentajes de variación en la glucemia basal y en la hemoglobina glucosilada fueron: el grado de obesidad durante el primer año y el estado preoperatorio de diabetes respectivamente. El análisis de las necesidades de tratamiento antidiabético mediante el diabetes status score modificado señala al IMC preoperatorio, la edad y el sexo como factores predictores significativos. CONCLUSIONES: En pacientes intervenidos de cirugía con banda gástrica la pérdida de peso contribuye a mejorar la sensibilidad a insulina. Esta mejoría del metabolismo glucídico se ve influida por factores tales como el sexo, la edad, el tratamiento insulínico, el tiempo de evolución de la diabetes y el grado de obesidad preoperatorio

INTRODUCTION: The aim of the study was to evaluate preoperative factors associated with remission of diabetes and weight loss after laparoscopic gastric band surgery. MATERIAL AND METHODS: A retrospective cohort of 95 patients who had an adjustable gastric band placed were included. A preliminary descriptive study of prognostic factors was performed using the logistic regression model with SPSS 17.0. The independent variables were age, sex, body mass index (BMI), diabetes status and degree of obesity; dependent variables were the proportion of weight loss, change in diabetes status score and percent changes in fasting sugar and glycosylated hemoglobin. RESULTS: The variables that were significantly associated with the percentage of changes in fasting blood sugar and glycated hemoglobin were: the degree of obesity in the first year; preoperative and diabetes status respectively. The analysis of the need for antidiabetic treatment using the modified diabetes status score showed preoperative BMI, age and gender as significant predictors. CONCLUSIONS: In patients undergoing gastric band surgery, weight loss is the fundamental mechanism by which insulin sensitivity increases. This improvement in glucose metabolism is influenced by factors such as sex, age, insulin treatment, duration of diabetes and degree of preoperative obesity
